IMPROVEMENT IN SPlNNiNG=EVlACHINES.

Specication forming part of Letters Patent No. 123,221, dated January30, 1872.

SPECIFICATION.

I, GEORGE BERNHARDT, of Radcliffe, in the county of Lancaster, in theKingdom oi' Great Britain and Ireland, have invented Improvements inSpinning-Machines, of which the following is a speciiication.

Nature and Object of the Invention.

The object of my improvements in spinning- Inachines is to modify andarrange and make additions to them, so that all the full bobbins of aframe or machine may be simultaneously removed from the spindles andreplaced by empty bobbins in a very short time by means of. mechanismoperated upon by hand at one end of the machine, and thereby economisingtime a-nd labor and increasing production; and my invention consists inthe combinations, arrangements, devices, and mode of action hereinafterdescribed for attaining' the above-named object.

.Description cf the Accompanying Drawing.

Figure l, Sheet No. l, is a cross-sectional elevation of so much of aspinning-frame as will be necessary for eXplainin g myinvention; andFig. 2, Sheet No. 2, is a front elevation of the same, showing only onespindle and part of the front covering-plate h supposed broken away.Fig. 3, Sheet l, is a detached side view, and Fig. 4, Sheet l, an endview of the bobbins employed.

The improvements are illustrated as applied to a ring and travelersl'iinning-frame, more particularly intended for twisting threads, andcommonly termed doubling frames A, the two end frames; Al, spindlefootstep rails; A2, upper spindle-bearing rails; A3, roller beams; n,draft or other rollers; b, tin drum or roller for driving the spindles cand l is the ring or copping-rail. All the above-mentioned parts areordinary. e are shafts for actuating the coppin g orring-rail, theseshafts having toothed wheels e1 upon them, which gear with rackteeth inbars e? that slide vertically through bearings in the upper and lowerspindle-rails A1 and A2 and the ring or copping-rails are secured to theupper ends of the said bars e2. The shafts e receive oscillatorymovement to distribute the thread from the ordinary mechanism usuallyemployed, which acts upon the toothed wheels e3, which are loose uponthe shafts. but when the machine is spinning these wheels are made fastto the shafts by clutches e4, that slide on a iixed key. The clutchesare acted upon by clutch-levers e5, and the clutches for both sides ofthe frame are connected so as to be simultaneously acted upon bysecuring both clutch-levers upon a cross-shaft, es, carried by bracketssecured to the end framing. The two shafts c are geared together a-t theend of the frame by means of a toothed wheel, e", on each of the shaftse, and two intermediate wheels, e8 and e9, and one of the latter wheelse8 is in gear with a pinion,fl, on the boss of a hand-wheel, f, loose onthe end of' pitch-lines of the toothed wheels last referred to are shownin Fig. l in peculiar dotted line. hen the machine is spinning thehand-wheel fis free to oscillate to and fro with the movement of thecopping or ring-rail d. b1 is a hand-wheel, fast on the end of thetin-roller shaft, for turning the tin-drum when required. g ls\a railpassing from end to end of the machine, and through this rail there is ahole for each spindle just large enough to pass over the brad 7 cl uponeach spindle having the pins in it that drive the bobbin, but smallerthan the head of the bobbin. This rail serves to lift the bobbins whendoiiing and rests when the machine is spinning upon the upperspindle-rail. The lifting-rail g is mounted upon the upper ends ofvertical bars gl sliding in bearings in the spindle-rails, these barshaving racleteeth, each rack gearing with awheel, g2, loose upon theshaft e, so that they do not move with the shafts when spinning, butwhen these shafts oscillate beyond the extent of movement required inspinning a pin in a boss, g3, fast on the shaft e, comes against a pin011 the face of the wheel, and thus causes the rail gto be lifted. Eachof the wheels g2 also gears with a rackbar, h1, sliding vertically onsuitable guides secured to the spindle-rails. The upper end of each ofthese rack-bars has a bracket, h2, secured to it, to which the thinplate h, of metal, is attached. These plates are for the purpose ofcovering and uncovering the empty bob bins and mechanism for carryingthe same, hereinafter described. The covering-plate h is shown in theposition it occupies when the the sha-ft of the tin-drum or roller b.The

machine is spinning on the left of Fig. l, and in the position itoccupies when dottlng on the right of the same figure. 7c is a shaftpassing from end to end ofthe frame in suitable bearings in the frame.Upon this shaft, at suitable intervals, disks k1 are keyed, each havingtwo crank-pins k2, to each of which one end of a link, k3, is jointed,the other end being jointed to a rod, k1, sliding in a bearing securedto the under side of the roller-beam. To the ends of the slide-rods (thenumber being according to the length of the frame) a rail, 7J, issecured, which passes from end to end of the frame 5 and to the rail atube, k7, is secured to come opposite to each spindle. These tubes aremade of metal, and are open in front, except just at their upper ends,the opening being sufficient to allow the barrel of the bobbin to passthrough when slightly lowered, so that the head of the bobbin will passbelow the bottom of the tube. The empty bobbins are passed into eachtube while the machine is spinning' through a hole in the roller-beam,which is made opposite to each tube, and the bobbin rests upon a tableformed by a plate, las, (one on each side of the frame,) passing fromend to end of the machine and carried from the roller-beam by bracketskg. The vertical part of the table-plate also serves as a cover, and init slots are formed for the brackets h2 to pass through that carry themoving covering-plate h. There is a handle, k1", upon the end of theshaft k, by partly rotating' which until it comes against a stop-pin,kx, in the frame the empty bobbin-rails k5 on both sides aresimultaneously pushed outward until the center of the bobbins come overthe ends of the spindles.

I will now describe the mode of dofling by the mechanism. WVhen thebobbins are full the copping mechanism is thrown out of gear with thesha-tts by moving the clutch-levershaft e5, and then the copping orring-rails (l are lowered by the hand-wheelj', while a small portion ofthread is wound upon the lower part of the brad7 01. Then the machine isstopped. The hand-wheelf is then turned back, and the ring-rail Z islifted to the position shown on the right of Fig. l, the hinged-wirecurl or guide-board l being lifted into the position shown. The samemovement which lifts the ring or copping-rail also carries theliftingrail g to the position shown on the right of Fig. l, where itsupper surface is just level with the empty-bobbin table-plate 7c8 andjust above the tops of the spindles c, and the same movement of thehand-wheel also brings the coveringplate h into the position shown onthe right of Fig. l. The handle 7610 is now moved till it comes againstthe pin kx, and the empty bobbins are by this movement brought over thespindles, as shown, on the right of Fig. l; then the lifting-rail gislowered slightly by the handwheel f' to bring the heads of the bobbinsclear of the bottom of the tubes k7, and the handle k1" is then turnedback to bring the tube-rail 7.5 back into the position shown on the leftof Fig. l. The empty bobbin-rail g and ring-rail d are then lowered andthe clutches e4 are brought into gear again, and. this completes theoperation, which takes from fifteen to thirty seconds.

The collar upon the brad c1 is roughly milled on its edge, and the lowerhead of each bobbin is notched, as shown by the detached views, Figs. 3and 4. This ronghening ofthe collar and notching of the bobbin isimportant, as it prevents the bobbin from turning and the thread fromuncoiling from the bobbin when lifted, and consequently when the fullbobbins are lifted the threads are broken with certainty between eachbobbin, and that part wound upon the lower part of the brad, leaving'the thread between the traveler and lower part ofthe brad ready to windupon the bobbin when the frame begins to work. full bobbins are pushedfrom the lifting-rail g by the empty bobbin-tubes L5, when they collieforward, and they fall into any suitable receptacles placed on each sideof the frame to catch them. I employ a receptacle formed by two framesjointed together to fold like a campstool, which can be easily carriedfrom one frame to another, as required.

When dofling it is an advantage to gear the rollers a on both sidestogether, so that they can be turned forward slightly (about one-thirdof a revolution of the front roller) to give slackness to the threadswhen doiing, which prevents breakage when the empty bobbins comeforward.

Ola/5ms.

1. The ring-rail d and the dofng-rail g, operated independently of eachother from the same shaft e, through the medium of the racks andpinions, or their equivalents, substantially as described.

2. The combination of the lifting-rail g and sliding-plate lb, as setforth.

3. The combination, with the spindles, of a stationary platform, kg,secured to the frame of the machine, for the reception of the bobbinspreparatory to transferring .them to the spindles, as described.

4. The combination of the ring-rail d, liftingrailg, platform la, a-ndsliding tube or case k7, all operating together, substantially asdescribed. l

5. The combination, with the brad c1, of the roughened collar, arrangedto insure the simultaneous breaking ot' the threads between the bobbinsand the brads by the eleva-tion of the lifting-rail g, substantially asdescribed.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
